I have both the AAC Element, Gen 1 and the Sparrow SS can. They both have their strong points. As said before, the Sparrow does have a first round pop when shot from a pistol where the AAC does not. Since I enjoy what I consider the best of both worlds, the Sparrow gets put on the rifles and the Element goes on the pistols. Yes, I do have a number of hosts for the cans. That’s that bad part of owning cans, threaded barreled guns tend to grab your attention. If you can only do one 22 can I would recommend the Sparrow if you don’t mind the first round pop from a pistol. It’s stainless steel and the company has great customer service where AAC is waning in that department since they got bought by Remington.
Two other things, do not shoot the 60 grain bullet, it does not stabilize properly and will damage the can with baffle strikes. Barrels 4.5 inches and less will keep all but the hottest 22 loads from going supersonic therefore eliminating the sonic crack.
Just my quarter’s worth adjusted for inflation.
